Specification of Letters Patent.

Application filed April 10, 1920. Serial No. 372,942.

To all whom it may concern:

Be it known that I, ARTHUR EDWIN LEIGH SoANEs, a subject of the King ofGreat Britain, and a resident of Strathfield, Harboro cooling watercirculates. The invention has particular reference to the locationandarrangement of the tubes'withinthe condenser.

Theobject of the invention is to reduce the pressure drop of the steampassing through the condenser due to the friction of the steam passingover the condenser tubes.

The accompanying drawing is a cross sectional view of'a surfacecondenser with its tubes arranged in accordance with the presentinvention.

The condenser shell is indicated in dot and dash lines at 1 with a steaminlet 2 at the top and an air outlet 3 with the usual bafile plates nearthereto. tudinal stay is shown at 5. As will be seen from an inspectionof the drawing, the arrangement of the tubes 6 is such that the steamentering the inlet 2 will flow downward between the tubes insubstantially straight linesin the upper part of the nest of tubes bothfrom the top and at the sldes parallel with the direction of the flow atthe'inlet until it reaches the center portlon of the tube nest when theremaining uncondensed steam will follow irregular paths be-.

tween the remaining tubes in the lower part of the condenser toward theair outlet'3.

In condensers of large size it is very desirable to reduce the loss ofhead through the condenser to a minimum and according to the inventionthis is accomplished by arranging the tubes so that at the inlet and atthesides of the condenser the parallel lines are substantially parallelwith the flow of V steam at the inlet, while in the center of thethrough which the The usual 'longicondenser and near the air outlet, theparallel lines lie in a direction substantially perpendicular thereto.Preferably the surfaces of intersection of the two arrangements oftubing are planes, which facilitates manufacture.

While I have shown my invention in but one form, it will be obvious tothose skilled in the art that it is not so limited but is susceptible'of various other changes and modifications without departing from thespirit thereof and I desire, therefore, that only such limitations shallbe placed thereupon as are imposed by the prior art or as arespecificall What claim is:

1. A condenser of the surface type having inlet means, outlet means andwater tubes, a group of said tubes being arranged in lines parallel tothe flow of steam through the inlet and at the sides thereof and othergroup or groups'of tubes arranged in parallel lines perpendicularto thelines of the first group.

set forth in the appended claims.

2. A condenser provided with a steam inlet 2' and an air outlet, a groupof tubes arranged in lines parallel to the flow of steam through saidinlet and at the sides thereof, and other tubes within said condenserarranged in lines perpendicular to the lines of the first group andbetween the first group and the air outlet.

3. A condenser having a steam inlet, an airroutlet and a baffle platecontiguous to said air outlet, a group of cooling tubes wlthin thecondenser arranged in llIlBS parallel to 1 the direction of flow ofsteam through the inlet and a second group of cooling tubes arranged inlines perpendicular to the lines of the first group and being overlappedat the ends by tubes of the first P in lines parallel to those of thesecond group and located between the first two groups and said baffleplate.

In testimony whereof, I have hereunto subscribed my name this twelfthday of March, 1920.

ARTHUR EDWIN LEIGH SCANES.
